What went wrong with this marinade?

There were some obvious issues with the recipe (listed cumin seeds as an ingredient, not in the actual recipe, called for orange in the ingredients and then used lemon in the recipe) but this marinade was the worst thing I have ever made. It had cumin seeds, coriander seeds, chili flakes, marjoram, garlic, olive oil and salt and I ground it all in a food processor and tasted like chili flavored soap. Thoughts?
